I have written to the NYC Parks Commissioner to have a memorial erected in the Ramble in honor of Manuel Sobral who was killed during the landscape project earlier this year.
If you would like to support this effort here is the Commissioner's contact:

I believe that this man deserves a memorial for the heavy price he paid during his work for the Central Park Conservancy. Too often we pay homage to the rich and famous and neglect to acknowledge the many lesser known men and women that contribute to making this park a beautiful place.
Recently the Ramble was opened up to the public after several months of closing for the landscape work that Mr Sobral was instrumental in making happen.

I am sure his family will be honored if they were consulted for this small token of appreciation for his work and the ultimate price he paid for this landscaping project. I am also certain that all his fellow workers will be honored to know that though they were paid for their hard laborious work, we appreciate the toll it sometimes takes on them.
The memorial may also serve to remind many of us who visit the Ramble, that more than money is sometimes spent to make accessible all the beauty and solace that special place offers.
